He intends the creature to be beautiful, but when it awakens he is disgusted. It has yellow, watery eyes, translucent skin, and is of an abominable size. Victor finds this revolting and although the creature offers him no harm (in fact, it grins at him and reaches its hands out innocently to its creator), Victor runs out of the room in terror, whereupon the creature disappears. Shock and overwork cause Victor to take ill for several months. After recovering, in about a year's time, he receives a letter from home informing him of the murder of his youngest brother William. He departs for Switzerland at once.

Funny how people call that creature Frankenstein, when in fact it was the monster's creator Victor who bore that name.
